JOHN G. UTZ, OF DETROIT, MICHIGAN, ASSIGNOR TO CHALMERS-DETROIT `MOTOR COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

LUBRICATOR.

Application filed December 5, 1908. Serial No. 466,158.

To all whom z' may concern Be it known that I, JOHN G. U'rz, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Lubricators, of which the following is a specification, reference being had therein to the accompanying drawings.

It is the object of the invention to provide means for lubricating the parts of a rapidly revolving mechanism, such for instance as the main clutch in an automobile transmission.

To this end the invention consists in the means employed for propelling and directing the oil by the coperation of its owii inertia. v y

The invention further consists in the peculiar construction as hereinafter set forth.

In the drawings-Figure l is a longitudinal section through a motor tly wheel', its inclosing casing, and a friction clutch arranged'within the fly wheel; Fig. 2 is a' section at right angles to Fig. l, showing the clutch in elevation. i

A is the engine shaft, Il the fly wheel, and C the inclosing casing.

D is a friction clutch arranged within tl e space inclosed by the rim of the fly whel, and through the medium of which power is transmitted from the engine 'to the driven shaftgE. l

It is the particular object of the invention to provide means for lubricating the parts of this friction clutch which, as illustrated, is of the multi-disk type.. This is' accomplished by forming in the rim of the {iy wheel B one or more passages F, which are The oblique to the radius of the wheel. lower portion of the casing C has formed therein an oil chamber and a portion of the ,periphery of the wheel B .is constantly ini-4 mersed iii the. oil. Thus, when thevwheel is in rapid rotation, the oil entering the oblique passages Fwill be driven by the wheel, and,

by reason of its inertia, will be propelled inward and thrown against the clutcliD.

The greater/the speed of rotation 'of the wheel the greater the force with which the oil will be t'liro'wn inward, and consequentlyv the clutch is constantly supplied with lubricant. whenever the mechanism is in operation.

What- I claim as my invention is:

l. The combination with a casing having an oil chamber in thelower portion thereof, of -a device to be lubricated arranged within said casing, and, means also within said casing rapidly revolving through the oil and radially spaced from said device to be lubricated, said means having a portion provided with a passage extending therethrough at an angle to the radius thereof for jetting the oil radially inward to said device through the open'space between said device and said passage.

2. The combination with a casing having an oil chamber in its lower portion, of a de- Vvice to be lubricated within said casing,l an

annular member surrounding and spaced from said device revolving through the oil, said annular member being provided with a.

passage therethrough oblique to the radius rapid rotation of the fly-wheel and the' inertia of the oil.A

In testimony whereof I atliX my signature 1n presence of two witnesses.
